As soon as Tatsuya woke up, he immediately found that there was someone beside him in the bed, the person in question is currently hugging his waist; he removed the blanket that was currently covering his body and the person in question, revealing a peacefully sleeping Miyuki who is currently hugging her brother's waist, Tatsuya does not want to wake her up as it is still early in the morning, and he also does not want to skip his daily run so he carefully removed Miyuki's hand so he can go and start his day which he successfully did it, but Miyuki did groan a bit as she loses the warmth while keeping her good sleep but still asleep nevertheless.
He also wondered why Miyuki was sleeping in his bed, but he remembered that she was the one who requested that she want to sleep together with him (not in a sexual way). Tatsuya even teased his sister saying that she's grown up and wanted to do adult things with her brother which causes her to blush and started freezing everything near her she eventually calmed down when Tatsuya told her that he was just joking which earn his pinch the waist and told her that he's fine with sleeping with her which Miyuki gave him a kiss on the cheeks and a beautiful smile before rushing towards her room to change into her nightwear.
Tatsuya grabs his change of clothes to the bathroom to change as changing in his bedroom is just suicidal. He does not want that cliche thing to happen to him after he changed clothes suitable for his daily run; he got out of their house and ran 5 km before going to Kyuuchouji Temple where his current master in hand-to-hand combat resides.
While Tatsuya may have talent when it comes to fighting, it is not a bad idea to hone your talent even more, as efforts will only get you somewhere limited. Tatsuya also saw this personally in his past life when knights train so intensely only to get defeated by another knight who is newer, younger, and less experienced in the older knight.
While Tatsuya's skills in the sword are at the Grandmaster level, another weapon might be only at the advanced level, trying to reach it at the master level and maybe hoping to push it into the Grandmaster level.
By the time Tatsuya entered the gate of the temple, he was attacked by other disciples of Kokonoe Yakumo, a famous ninjutsu user, and someone who passed on traditional shinobi magic. Yakumo is also the master of Tatsuya.
One disciple tried to kick Tatsuya in the stomach so that they would get him to run out of air, but their movements are too slow for Tatsuya, who have been in countless wars in his past life, while his skills are top notches he still trains, so his skills will not rust.
Tatsuya grabs the ankle of the disciple and tries to kick him and swung him to the other disciple, causing them to fall, while the others try to land a surprise attack that still fails as Tatsuya counters them easily, causing them to fall on the ground to tend their injuries.
As he was walking to find where his master is, he noticed someone snuck around his back, so he backhands it only for the attacker to lean backward, causing Tatsuya's attack to be missed. Tatsuya looked at his master who had a carefree smile and just stood there.
"That's a good one Tatsuya" Kokonoe said while rubbing his chin, which Tatsuya just nodded in response before dashing towards him and throwing a punch and followed by a kick which Kokonoe easily evaded, Tatsuya saw this as a chance so Tatsuya gave Kokonoe a roundhouse kick which connected but Kokonoe used ancient magic to absorb its kinetic energy from the kick which where he did a One Leg Sweeps causes Tatsuya to fall and saw Kokonoe smiling where he offer Tatsuya a hand which he accepted.
'I still have too much to learn, even though I'm unparallel in using a sword I don't want it to be my weakness
Kokonoe leads Tatsuya towards the shrine and sat there where he offered tea, Tatsuya to Kokonoe talked for a bit before going home.
...
After he got home and entered the house, Tatsuya saw Miyuki have already finished making breakfast for the two of us, so I did not make her wait any further and sat in front of the table as we started to eat.
Tatsuya told his sister about what they did during training with Kokonoe.
After breakfast, they hang out in the living room where Miyuki asked about his life in the past and what it was like to live in an era when technology did not exist yet.
"It's quite nice, the air is so fresh and can be relaxing, that time didn't have that much entertainment so when people want to relieve stress they go to sleep under a tree or visit a brothel" Tatsuya said causing Miyuki to blush.
"S-So Onii-sama also visit that kind of place?" Miyuki asked causing Tatsuya to laugh at her making Miyuki even redder and started to hit Tatsuya in his chest, he just let her as it did not hurt, it is also nice that the bond together like this previous Tatsuya in this era act reserved towards his sister because of his status as a Guardian.
"Of course not, even if I wanted to I can't, I'm a king remember? it would tarnish my reputation if I go to places like that, but daughters of the nobles wanted to bed with me but in the end, I refuse, the official even encourage me to have a harem but still refused as I'm a bit too focused on ruling the country... its probably the reason why I failed at the end..." Tatsuya said, as he muttered the last part and the air became colder, it disappeared.
"S-So Onii-sama want to have a harem?" Miyuki asked.
"Huh? I mean yeah I do, I did miss a lot in my past life and want to enjoy myself in this era, my sense of morals is messed up huh, it's probably because of the two memories I have" Tatsuya said.
"Didn't Onii-sama have a wife in his past life?" Miyuki said, with a sad tone.
"OH! Hahaha, I remember, Guinevere Is my wife in name only as one of my loyal knights is her lover, his name is Lancelot my strongest knight, and his strength is only below mine" Tatsuya said.
"Why did Onii-sama marry her if she already has a lover?" Miyuki asked.
"It's because she's a princess, and also one of my close friends, so she decided that she will be married to me in the name so that the officials stop their nagging as I also keep complaining to her, that the official can't stop their nagging on me finding a wife, I bet Guinevere gave that proposal so that I can stop my nagging, good times" Tatsuya said as he chuckled remembering the past.
"people in the past are weird" Miyuki said as she looked at her brother weirdly.
"So what about your family in the past Onii-sama?"
"Oh... that, it's quite an ugly family" Tatsuya said with a frown.
"Sorry for asking Onii-sama, if you don't want to talk about it's fine" Miyuki said looking at her brother's uncomfortable expression.
"Yeah it's fine, I'll tell you, I thought I'm an orphan as I grew up alone, but later I found out that I do have parents, my father, the king told me that he sent me away to protect me and he knows the I will go back to them, which I didn't mind and also understood that they care about me, I also have an evil half-sister, and... and found that I also have a son that was born from an incestuous relationship with my half-sister... which I didn't know about until she said it herself that she wanted our son to be the next heir in front of my face"
She also told me that she drugged me, causing me to lose all reasons and take her to bed at that time, which resulted in Mordred being born. The reason I did not remember because of the side effects of the drug" Tatsuya said with a wry smile.
"incestuous relationship with her half-sister, incestuous relationship with her half-sister, incestuous relationship with her half-sister, incestuous relationship with her half-sister, incestuous relationship with her half-sister, incestuous relationship with her half-sister, incestuous relationship with her half-sister!" Miyuki kept repeating those words and made Tatsuya worry about her when he was about to ask her to yell.
"Onii-sama!" Miyuki said as he grabs Tatsuya on the shoulder, Tatsuya wanted to remove her hands from his shoulder to calm her down because she seems excited for some reason and keeps repeating those words, but he cannot remove her hands from his shoulder, but her grip is too strong like what happened to her.
"Onii-sama! What you you think about Miyuki?!" Miyuki asks Tatsuya to look at her weirdly.
"Huh?" Tatsuya let out a dumb sound.
